Inventor: HWANG SEONG UK
IPC: H03K5/00
Filed: 1999-12-30
Abstract: PURPOSE: A voltage level shift circuit having high current driving capacity and high output voltage level is provided to produce a differential voltage corresponding to a reference voltage using a differential amplifier while controlling the level of the differential voltage with an extra control signal. CONSTITUTION: In the voltage level shift circuit, an input unit having a differential structure(300) receives a reference voltage from a reference voltage generator and the ground voltage as the first and second input voltages(INN,INP). An input load(310) is connected to the input unit(300). A signal converter(320) converts the differential signals from the input unit(300) into a single signal. An output unit(330) responds to the single signal from the signal converter(320) and sends the differential voltages to the first and the second differential voltage output terminals(OUTN,OUTP). A common mode feedback unit(340) responds to the output unit(330) and the differential control signals(CN,CP) and controls the differential voltage range of the output unit(330).

Title: Virtual environment data browser
Inventor: GALLERY RICHARD DAVID
IPC: G06F17/30
Filed: 1998-05-29
Abstract: PURPOSE: A virtual environment data browser is provided to decrease load of calculating by arbitrating of a systematic data structure. CONSTITUTION: A data browser is described for accessing data defining virtual environments via the Internet/World Wide Web. Where the data defining objects to appear within the virtual environment is in the form of discrete geometrical components, with each object being arranged as a hierarchy linking the components and with transformations specifying the translation of vertex locations for a child component to the coordinate system of its pa rent, the browser maintains a record of previously calculated transformation products. Each time the browser updates its generated representation of the virtual environment it checks which components have moved, and hence which transformation multiplications must be updated, and otherwise recalls the result of the previous calculation.

IPC: H04N19/593
Filed: 1997-11-25
Abstract: PURPOSE: A data efficient quantization table for digital video signal processor is provided to modify the characteristics of compression/decompression tables to facilitate data throughput and memory efficiency. CONSTITUTION: An MPEG coded and compressed video signal is received and decompressed for display. Prior to storing frames required for motion compensation in memory, pixel blocks are recompressed by quantizing DPCM(differential pulse coded modulation) prediction error values to reduce bandwidth and frame memory requirements. Fixed length quantization and dequantization tables have N levels(e.g., 15 levels), and each level has an associated output symbol of predominantly M bits(e.g., 4 bits), except that at least one of said N levels(e.g., level 7) is defined by a unique short symbol having less than M bits(e.g., 3 bits). One of the M bits may be reserved as a sign bit. Each time a short symbol is used to represent a data value, bandwidth and memory are reduced and/or preserved for other uses, for example, inserting overhead data into a fixed-size data stream. For large sequences of data, such as exists for video data for example, the reduction in memory and bandwidth is significant.

Abstract: A device (1) for carrying out continuous electrolytic precipitation processes has a cathodic live cylinder (3) whose top surface is electroconductive over its whole useful width. An anode A is arranged concentrically to and spaced apart from the cathodic live cylinder (3). An electrolyte flows through the space (6) separating the live cylinder (3) from the anode A. Shielding strips (9, 9') associated to the live cylinder (3) are located between the cathodic surface of the live cylinder (3) and the anode A and electrically shield the marginal regions of the live cylinder (3), thus protecting them from electrolytic coating. The useful region N of the live cylinder (3) for carrying out the electrolytic precipitation processes is located between the shielding strips (9, 9'). The side of the shielding strips (9, 9') facing the useful region N has a shoulder (25') which reduces to zero the thickness of a metal strip to be produced or coated on one side, in the marginal region of the metal strip up to the shielding strip edge, so that no coating is deposited on the live cylinder outside the useful region N. The device (1) is useful both for electrolytically producing metal strips and for electrolytically coating one side of metal strips.
